【摘要】：本試驗旨在研究奶粉增強劑對飼喂奶粉犢牛生長性能及健康狀況的影響。選擇體重相近的新生犢牛28頭,隨機分成2個處理,每個處理14頭,公、母各半。對照組飼喂奶粉,試驗組飼喂90%奶粉+10%奶粉增強劑。試驗期為10周。結果表明:在6~8周齡階段試驗組母犢平均日增重顯著高于對照組(P0.05),試驗期間各處理對犢牛干物質采食量和飼料轉化效率無顯著性影響(P0.05);在0~10周齡階段試驗組母犢體高變化率顯著高于對照組(P0.05),同期試驗組公犢的體高變化率高于對照組,但差異不顯著(P0.05);試驗組公犢、母犢10周齡的體軀指數均顯著高于對照組(P0.05),各處理組的體長指數差異不顯著(P0.05);試驗期間試驗組與對照組犢牛腹瀉率比為1:2.25,發(fā)熱率比為1:4.5。綜上可知,在奶粉中添加奶粉增強劑可提高犢牛日增重,改善犢牛體尺,降低犢牛哺乳期的腹瀉和發(fā)熱情況。
[Abstract]:The purpose of this experiment was to study the effect of milk powder intensifier on growth performance and health status of milk powder calves. 28 newborn calves of similar body weight were randomly divided into 2 treatments, 14 in each treatment, male and half in female. The control group was fed with milk powder. The test group was fed with 90% milk powder 10% milk powder enhancer for 10 weeks. The results showed that the average daily gain of calves in the test group was significantly higher than that in the control group at the age of 6 ~ 8 weeks, and the dry matter intake and feed intake of calves were significantly higher than that of the control group during the experiment. The change rate of body height of female calves in the test group was significantly higher than that of the control group at the age of 10 weeks, and the change rate of the body height in the experimental group was higher than that in the control group at the same time. However, there was no significant difference in body length index between the test group and the control group (P 0.05), the body index of the female calf in the test group was significantly higher than that of the control group (P 0.05), and the body length index of each treatment group was not significantly different from that of the control group (P 0.05). During the trial period, the diarrhea rate and fever ratio of the calves in the test group and the control group were 1: 2.25 and 1: 4.5 respectively. Adding milk powder to milk powder can increase the daily gain of calves, improve the body size of calves, and reduce the diarrhea and fever of calves during lactation.
